Problems solved by technology

This kind of scroll compressor, especially when it is used in equipment with high output air pressure requirements (such as large aircraft), the working end face of the fixed scroll is easy to be worn due to the swing of the movable scroll when it is working. It will reduce the output air pressure and cannot meet the requirements of use.

Embodiment 1

[0017] The manufacturing method of the fixed scroll on the scroll compressor of the present invention includes the following steps:

[0018] (1) The base is made of steel material, and an involute vortex groove is machined on the working end surface of the base. The vortex groove has a bottom surface and two side walls;

[0019] (2) Simultaneously sinter the spherical copper powder layer on the working end surface of the substrate, the bottom surface of the vortex groove and both side walls, and the thickness of the spherical copper powder layer is 1.2mm;

[0020] (3) Put the liquid self-lubricating material in the vacuum furnace, immerse the substrate in the self-lubricating material, and then evacuate the vacuum furnace. After 30 minutes, open the vacuum furnace and take out the substrate to obtain the finished static scroll. , Wherein the self-lubricating material consists of 2.5% by mass molybdenum disulfide and 97.5% by mass polytetrafluoroethylene emulsion.

Abstract

The invention discloses a production method of a static scroll plate on a scroll compressor. The method comprises the following steps: 1, processing a scroll groove on the work end surface of a substrate; 2, simultaneously sintering spherical copper powder layers on the work end surface of the substrate and the bottom and the two sidewalls of the scroll groove; and 3, putting a liquid self-lubrication material in a vacuum furnace, immersing the substrate in the self-lubrication material, and evacuating the vacuum furnace to make the self-lubrication material permeate into gaps between all spherical copper powders in the spherical copper powder layers. The method allows the work end surface of the produced static scroll plate on the scroll compressor and the bottom and the two sidewalls of the scroll groove to respectively have a self-lubrication effect, so the static scroll plate is basically not worn under conditions with high output air pressure requirements.

Description

Technical field [0001] The invention relates to a fixed scroll on a scroll compressor and a manufacturing method thereof. Background technique [0002] At present, there is a scroll compressor used in air conditioners. Its working parts are mainly composed of a movable scroll and a fixed scroll. The working end of the fixed scroll is provided with an involute scroll groove, and the movable scroll The working end surface of the disk is provided with an involute scroll body. After the fixed scroll and the movable scroll are assembled together, the vortex groove and the scroll body are arranged at 180 degrees to each other, and the static scroll is not stationary. When the moving scroll is driven by the crank to swing eccentrically, the air in the groove of the static scroll is compressed and discharged. This kind of scroll compressor, especially when it is used in equipment with higher output pressure requirements (such as large airplanes), the working end surface of the fixed scr...
